Bug 489303

Description Pierre-Charles David 2016-03-09 11:21:46 EST

Steps to reproduce, with Sirius-defined properties views installed/enabled.

1. Make sure the properties view is visible.
2. Create a plain (non-Modeling) projet with a sample.ecore inside (it probably works the same with a Modeling project, but I have not tested).
3. Create a new representation file (sample.aird) for the Ecore, and enable the "Design" viewpoint from "Ecore Tools" .
4. Select the sample.ecore from the Model Explorer. The properties view shows 'No properties available', OK.
5. Create a new diagram on the root EPackage in the ecore. The diagrams opens, and we have the expected tabs in the properties view (the "General" one from default rules, and the legacy ones).
6. Close the diagram and select again the sample.ecore in the Model Explorer. 4 identical exceptions are thrown (see below), which seem to indicate that the legacy bridge considers that the GMF-provided legacy are applicable to the element, but calls them in an invalid context.
